Gigabit connection and router, but I only get 100 Mbps on my PC

Question

I got a gigabit connection from my ISP (with PPPoE connection). Tested with the cable directly in the PC, works great, I get 1000 Mbps.

I bought an ASUS AC55U router, which claims to have gigabit ports, but if I put the cable in the router and connect the pc to the router, I only get 100 Mbps speeds. The connection status claims the speed is 1.0 Gbps:

I have a CAT 5E 4 pair cable, and as I mentioned before it works fine if I plug it in directly in the PC. All the drivers are installed, router has latest firmware.

I have no idea where else to look. I don't have any other gigabit routers to try.

Solution

1. Maybe your ethernet cable doesn't support a 1Gbit/s connection (physical problem).

2. Maybe you have to activate Gbit-LAN in your router settings. You can get there by typing in ipconfig (on windows) and type in your gateway address into your browser.

Good Luck.

Hi, thanks for your answer. The cable does support gigabit connection. If I plug in directly into the computer, it works fine. I have also checked the settings on my router, and there is no option for setting gigabit (it should be enabled by default). The computer also sees the connection to the router as gigabit (see screenshot)

Hey Nini. Only because the computer sees the 1Gbit connection, doesn't mean that it really is one. The router could also just send, that it is trying to send 1Gbit, but is failing. Has to be a physical problem between router and computer or directly on your computer Good Luck
